If you get hatchery chicks there will probably be a few like that. They will do okay. If you get more hatchery chicks, check them out right away--sometimes they can be taped and fixed during the first week of life. Don't ever breed a chicken with curled toes because it can be hereditary. Sometimes curling of toes is from a riboflavin deficiency (Vitamin B2) but those are usually curled under. The poultry pedia link that Kathy gave is one of the most helpful for feet and leg problems.
